FAQ

Chess.com and Lichess. Enter your public username on either platform and we fetch your most recent games automatically.
Each move is scored from how much winning chance it gave up, using the same win-percentage model as Lichess and Chess.com. The per-game number is a blend of a volatility-weighted mean and a harmonic mean, so a single blunder weighs realistically instead of being diluted by easy moves.
